FAQ
Frequently asked questions
Everything you might want to know about disposable email and how TempMail works.
Is it really free?
Completely. No signup, no payment, and no limit on how many addresses you generate.
How long does an address last?
Your address stays active while you are using it. Need something that vanishes fast? Try our 10 Minute Mail — it self-destructs on a countdown.
Can I send emails?
No, it is receive-only by design. You get emails and OTP codes, but you cannot send mail from a temporary address.
Is opening messages safe?
Yes. Every message is sanitized on our server and rendered inside a sandbox, so scripts and trackers cannot run on your device.
Can someone else read my inbox?
Only the browser that created an address holds its secret token, so no one else can read it. Still, treat disposable inboxes as public and never use them for sensitive accounts.
Do you keep my messages?
Only long enough to show them to you. Inactive inboxes and their messages are deleted automatically, and you can delete anything yourself at any time.
Which domains can I use?
You can pick from the domains shown in the address bar when you generate an inbox. Premium users can also choose a custom local-part.
Do you have an API?
Yes — see the API page for endpoints and examples to create inboxes and read mail from your own code.
